AV apparatus and method for controlling the same

1. An audio-visual (AV) apparatus comprising: an infrared ray receiver configured to receive an infrared ray command; a radio wave receiver configured to receive a radio wave command; a controller configured to accept at least one of the infrared ray command and the radio wave command, and to control a plurality of modules to a state of corresponding to the accepted command; a reception controller configured to control the controller to accept the infrared ray command when one of the infrared ray command and the radio wave command is received within a previously set predetermined time from the reception of the other of the infrared ray command and the radio wave command, while the AV apparatus is set in an infrared and radio combination mode in which the infrared ray command and the radio wave command are both accepted; and a transmitter configured to transmit a response signal via radio waves, the response signal notifying by controlling the reception controller that the infrared ray command is accepted, and the radio wave command is not accepted.

2. An audio-visual (AV) apparatus comprising: an infrared ray receiver configured to receive an infrared ray command; a radio wave receiver configured to receive a radio wave command; a controller configured to accept at least one of the infrared ray command and the radio wave command, and to control a plurality of modules to a state of corresponding to the accepted command; a reception controller configured to control the controller to accept the infrared ray command when one of the infrared ray command and the radio wave command is received within a previously set predetermined time from the reception of the other of the infrared ray command and the radio wave command, while the AV apparatus is set in an infrared and radio combination mode in which the infrared ray command and the radio wave command are both accepted; and a remote controller comprising an infrared ray transmitter configured to transmit the infrared ray command and a radio wave transmitter configured to transmit the radio wave command, the remote controller being configured to an infrared and radio combination mode where the infrared ray command and the radio wave command is transmitted, wherein the reception controller is configured to set the previously set predetermined time in such a manner that the previously set predetermined time corresponds to a time difference between a first time of receiving the infrared ray command and a second time of receiving the radio wave command when the remote controller in the combination mode simultaneously transmits the infrared ray command and the radio wave command.

3. An audio-visual (AV) apparatus comprising: an infrared ray receiver configured to receive an infrared ray command; a radio wave receiver configured to receive a radio wave command; a controller configured to accept at least one of the infrared ray command and the radio wave command, and to control a plurality of modules to a state of corresponding to the accepted command; a reception controller configured to control the controller to accept the infrared ray command when one of the infrared ray command and the radio wave command is received within a previously set predetermined time from the reception of the other of the infrared ray command and the radio wave command, while the AV apparatus is set in an infrared and radio combination mode in which the infrared ray command and the radio wave command are both accepted; and a switch module configured to cancel a radio wave mode in which the AV apparatus is configured to accept only a wave command, based on a predetermined infrared ray command when the AV apparatus is in the radio wave mode, wherein the switch module is configured to display a guidance of switching off the radio wave mode with the predetermined infrared ray command when an infrared ray command is received by the infrared ray receiver when the AV apparatus is in the radio wave mode.

4. An audio-visual (AV) apparatus comprising: an infrared ray receiver configured to receive an infrared ray command; a radio wave receiver configured to receive a radio wave command; a controller configured to accept at least one of the infrared ray command and the radio wave command, and to control a plurality of modules to a state of corresponding to the accepted command; a reception controller configured to control the controller to accept the infrared ray command when one of the infrared ray command and the radio wave command is received within a previously set predetermined time from the reception of the other of the infrared ray command and the radio wave command, while the AV apparatus is set in an infrared and radio combination mode in which the infrared ray command and the radio wave command are both accepted; and a switch module configured to cancel an infrared ray mode in which the AV apparatus is configured to accept only an infrared ray command, based on a predetermined radio wave command when the AV apparatus is in the infrared ray mode, wherein the switch module is configured to display a guidance of switching off the infrared ray mode with the predetermined radio wave command when a radio wave command is received by the radio wave receiver when the AV apparatus is in the infrared ray mode.
